Serial Interface
This chapter describes how to modify the interface board for RS-232
non-isolated (standard), RS-422 isolated/full duplex, or RS-485 isolated/half
duplex on the port and explains the configuration of the interface connector.
Install the jumpers and ICs on the board to configure it for the type of serial
communication you want to use.
Caution: When fitting driver circuit and straps before installing the
interface board, make sure that the circuit is not fitted
upside down (see front end markings in the illustration).
Also make sure that the “legs” of the circuit fit into the slots
in the socket and are not bent. Take ample precautions to
protect the board and circuits from electrostatic
discharges.
To configure the board as: Install these jumpers and ICs:
RS-232
1
2
Install a jumper on P3 so that the A is in the
middle of the jumper.
Install IC, 360-028-001 (MAX238) on SKT3
with pin 1 located where the arrow points to
SKT3 toward the bottom of the board.
RS-422

2
Install jumpers on P4 and P5.
Install IC, 360-027-001 (MAX1490), across
sockets SKT1 and SKT4 with pin 1 located
where the arrow is pointing to SKT1 towards
the bottom of the board.
RS-485

3
Install a jumper on P2.
(Optionally) Install a jumper on P5 if this
printer is going to be connected to the end of
the cable.
Install IC, 360-026-001 (MAX1480), across
SKT2 and SKT5 with pin 1 located where the
arrow is pointing to SKT2 towards the bottom
of the board.
